摘要
Unmethylated CpG oligonucleotides (CpG-ODN) increase adult and neonatal primary antibody responses to T-dependent antigens, at yet unidentified stages of antigen-specific B cell differentiation. In adult mice, a single dose of CpG-ODN adjuvanted tetanus toxoid (TT) vaccine markedly enhanced and prolonged splenic TT-specific antibody-secreting-cell (ASC) responses and significantly increased the size of the bone marrow (BM) ASC pool. Surprisingly, this was not associated with changes of germinal center (GC) numbers, size, apoptosis or function. In 1-week-old mice, CpG-ODN also enhanced TT-specific splenic ASC responses, but failed to correct limitations of the GC reaction and of the development of the BM ASC pool.
